Thriller was a television series which told a different story every episode. It usually starred great actors like Robert Powell, Tom Conti, Windsor Davies, the woman who lives next door to Hyacinth in Keeping Up Appearances and Marlene from Only Fools and Horses! There was invariably murder, intrigue and deception and more than a few plot twists. It was actually very similar to Tales of the Unexpected. I think you can get them all on DVD now, look them up if you like this sort of thing, top stuff!
